Penile deformity: With the improvement of people’s life and medical examination level, as well as the emphasis on healthy life, the number of outpatient consultation on penile deformity is much higher than before, and the detection rate is also much higher than in the past. In the case of outpatient clinics in pediatric urology at specialized hospitals, almost 10 out of every 20 patients have penile deformities, and these children are basically under 12 years old. There are several common conditions of penile deformity such as prepuce, prepuce, foreskin adhesion, and short penis appearance. Prepuce: When the foreskin cannot be turned up to reveal the glans, it is considered a prepuce. The circumcision needs to be treated surgically. Circumcision: There is no absolute standard for the determination of circumcision in the medical community, which leads to a great difference in the determination of circumcision and surgical indications by different doctors. However, what is currently accepted by pediatric surgeons is that in its natural state, a foreskin that exceeds 1.0 cm above the glans is called circumcised. Many reports show that circumcised children have a reduced incidence of glansitis, prepuce, and urinary tract infections after circumcision. Usually, it is quite common for children to have a certain amount of foreskin build up in front of the glans when they are young, and as they get older, especially after puberty, the head of the penis is gradually exposed. Although it is difficult to unify different doctors in terms of determining the circumcision and the indications for surgery, circumcision is certainly helpful for children who also have unexplained urinary tract infections, recurrent glansitis of the foreskin, and small lumps at the front of the foreskin. Foreskin adhesions: Foreskin adhesions are mainly the adhesion of the inner plate of the foreskin to the glans, which cannot be separated, and the accumulation of urine scale between the foreskin and the glans, etc. If recurring cases such as glansitis of the foreskin, circumcision is feasible.
